👉 Light particles, also known as photons, are fundamental entities that exhibit both wave-like and particle-like properties. These particles of light are massless and travel at the speed of light in a vacuum, approximately 299,792 kilometers per second. Photons are the quanta of electromagnetic radiation, meaning they carry discrete packets of energy proportional to their frequency, as described by Planck's equation (E = hν). They are crucial in various phenomena, from the photoelectric effect, where light can eject electrons from a metal surface, to the operation of solar cells and fiber optics. Unlike matter particles like electrons, photons do not have an intrinsic charge and do not interact via the strong nuclear force, making them unique in their behavior and applications in physics and technology.
